Description

PACKET FOR TOBACCO PRODUCTS AND FLAT BLANK FOR MAKING THE PACKET

The present invention relates to a packet for cigarette articles.

In particular, the present invention is particularly advantageous for the production of rigid packet cigarette packets obtained from each flat blank having a line of weakness made of cardboard, paperboard, plastic material or the like. The descriptions thereof will be referred to below, but do not limit the scope of the present invention accordingly.

Typical types of rigid packets, in the form of substantially parallelepipeds with rectangular cross sections and sharp longitudinal edges, suffer from the disadvantages resulting from anatomical shapes that are not liable to grip and the aforementioned longitudinal edges may cause wear to the pocket of the user's clothing. It has a disadvantage due to the fact that it causes.

To overcome this type of drawback, the prior art proposes various types of packets with rounded corners or even substantially oval or egg-shaped cross sections.

For example, WO-A-0144077, in the same applicant's name as the present invention, has all rounded longitudinal edges (i.e., of a packet) with a cavity facing the inside of the packet in a manner that eliminates the presence of sharp edges. A rigid cigarette packet of the hinged-cover type (parallel in the main direction) is shown.

Although this solution may limit the wear of the user's clothing, it does not significantly improve the grippability of the packet.

Moreover, the absence of sharp longitudinal edges has been found to lead to poor structural rigidity which results in easy deformation of the packet, especially at rounded corners.

Another disadvantage is that rounded corners can only be achieved as a major change to typical machines for packaging. In particular, it was necessary to perform a complex step of pre-deforming the area of the blank which would constitute the strip forming rounded corners upon completion of the packet.

Another conventional solution without most of the stated disadvantages is also known from patent publication IT BO98A000008, which discloses a hinged-cover type cigarette packet in the same applicant's name as the present invention, in which the longitudinal edge is the main direction of the packet. There is a connecting wall with the same variable dimensions along.

In this way, the peripheral extension of the packet has a maximum value and a minimum value in the grip area.

In other words, the connecting wall with variable dimensions allows the cross section of the packet to be reduced in at least one predetermined area and thus facilitates gripping.

Disadvantageously, this solution has been found to be problematic in the step of wrapping packets.

Indeed, typical cellophaning machines designed to wrap packets with transparent outer wrapping sheets for parallelepiped packets with sharp longitudinal edges have been found to be unsuitable for operation on these types of packets.

In particular, it is difficult to perform accurate wrapping of packets in areas with minimal cross sections, and also space is created by the resulting formation of unattractive creases and folds.

It is a primary technical object of the present invention to provide a packet for a tobacco article without the above mentioned disadvantages.

In particular, it is an object of the present invention to provide a rigid packet for a tobacco article that is easy to hold and at the same time easy to pack.

The indicated technical purpose and specific objectives are achieved by a packet for a tobacco article comprising the technical features described in independent claim 1.

Referring to the accompanying drawings, reference numeral 1 shows a packet for a tobacco article according to the present invention.

In the following description, reference is made to articles of smokers composed of cigarettes, and thus not limiting the scope of the invention.

The disclosed packet has a hinged-cover type, but the present invention should recognize that this is a hinged-cover or other type, or refers to a packet of any type of packet for tobacco articles.

The rigid type packet 1, which actually extends in the form of a parallelepiped with respect to the main direction ("A"), has a compartment designed to receive a group of cigarettes ("S") inside.

In particular, the main direction ("A") is the direction in which the packet 1 mainly extends along this.

In particular, the packet 1 has a front wall 2, a rear wall 3 facing the front wall 2, a pair of side walls 4, 5, a bottom wall 7, and a top wall 6. It includes.

The front wall 2 is substantially flat and extends parallel to the rear wall 3, while the two side walls 4, 5 (parallel to each other) traverse them.

The bottom wall 7 and the top wall 6 are perpendicular to the main direction "A" (in at least the closed configuration of the packet 1), and also the front wall 2, the rear wall 3, and The side walls 4 and 5 have a number of sides that extend.

It should be appreciated that the bottom wall 7 and the top wall 6 have the same peripheral extension "P".

As a result, the periphery of the bottom wall 7 is the same for the top wall 6 (numerically).

Moreover, the bottom wall 7 has the same shape as the top wall 6 but is offset with respect to it.

According to the invention, the packet 1 is at least one first corner wall 8 and at least one interposed between the side walls 4, 5 and the respective front wall 2 or the rear wall 3, respectively. It has a second corner wall 9.

In other words, the packet 1 comprises at least two corner walls which are inclined with respect to both the front wall 2 or the rear wall 3 and each of the side walls 4, 5.

The first corner wall 8 and the second corner wall 9 have a transverse dimension that can vary along the main direction "A" of the packet 1.

In particular, the first corner wall 8 and the second corner wall 9 have a transverse dimension which can vary linearly along the main direction "A" of the packet 1.

The term "transversal" is used to mean the dimension measured across the main direction ("A") of the packet 1 (especially on a vertical plane).

More specifically, each corner wall 8, 9 is between two edges 8a, 8b, 9a, 9b connected to the front wall 2 or the rear wall 3 and the side walls 4, 5, respectively. Extend from.

As a result, the measure of the distance between the two edges 8a, 8b, 9a, 9b of the single edge wall 8, 9 can vary along the main direction "A".

Thus, for different transverse cross sections of the packet 1 (ie perpendicular to the main direction "A"), there are different transverse dimensions of each corner wall 8, 9.

In order to keep the periphery (ie peripheral extension) of each transverse cross section constant, the first corner wall 8 is in a shape complementary to the shape of the second corner wall 9.

The term "complementary" in the present invention is used to specify that the change in the transverse dimension of the first corner wall 8 corresponds to the same and opposite change in the transverse dimension of the second corner wall 9.

In other words, since the increase in the transverse dimension of the first corner wall 8 corresponds to the decrease in the transverse dimension of the second corner wall 9 (and vice versa), the sum of the two transverse dimensions remains constant. do.

Advantageously, in this way, the sum of the transverse dimensions remains constant along the entire extension of the packet along the main direction ("A").

Moreover, in this way, even greater gripping properties are obtained without adversely affecting the packing, because the peripheral extension is constantly present even if there is a change in the shape of the packet along the main direction ("A"). Because.

This prevents the formation or folding of space in the cellophane work of the packet 1.

Preferably, the first corner wall 8 has an increasing transverse dimension towards the upper wall 6 and the second corner wall 9 also has a decreasing transverse dimension complementary to the first corner wall 8. .

The two edges 8a, 8b of the first corner wall 8 thus have extensions which diverge from one another along the main direction “A” towards the upper wall 6.

In contrast, the two edges 9a, 9b of the second corner wall 9 have extensions that diverge from one another along the main direction “A” toward the bottom wall 7.

More preferably, according to the embodiment shown, the edges 8a, 8b, 9a, 9b of the edge walls 8, 9 have a single curvature, ie they do not have a change in curvature.

In some embodiments (FIGS. 1-9B, 11A-14B), the edge walls 8, 9 are between a first end connected to the bottom wall 7 and a second end connected to the top wall 6. It extends along the entire extension of the packet 1.

Alternatively, as shown in FIGS. 10A, 10B, 15A, 15B, the edge walls 8, 9 have partial extensions, where one end is the bottom wall 7 or the top wall 6. While the other end is connected to the middle region of the longitudinal extension of the packet 1.

In the embodiment shown in FIGS. 10A and 10B, each corner wall 8, 9 has a trapezoidal shape. The first corner wall thus comprises a first half-part with a triangular shape with vertices at the bottom wall 7 or the top wall 6, and the front wall 2 or the back wall 3 and the respective side walls 4. 5) has a second half-part with a constant shape forming a bevel therebetween.

On the other hand, the second corner wall 9 forms a joining point between the first end and the front wall 2 or the rear wall 3 and the respective side walls 4, 5 located at the bottom wall 7. And between the second ends extending as edges.

Alternatively (FIGS. 15A, 15B, 16A, 16B), the edge walls 8, 9 have a trapezoidal shape. In a form similar to a triangular shape, the trapezoidal shape may extend over the entire length of the wall (FIGS. 16A, 16B) or just a portion thereof (FIGS. 15A, 15B).

Preferably, the edge walls 8, 9 have a substantially flat shape. In particular, they lie on each plane inclined at an angle equal to 20 degrees to 80 degrees, preferably 30 degrees to 60 degrees, more preferably 45 degrees to the adjacent side walls 4 and 5.

Alternatively, it should be appreciated that the edge walls 8, 9 may have curved surfaces for the connection between the side walls 4, 5 and the respective front wall 2 or the rear wall 3 (FIG. 13). To FIG. 14B).

In this embodiment, each corner wall 8, 9 has the shape of a cone or truncated cone.

Advantageously, in this latter embodiment (curved shape), the edge walls 8, 9 have a front wall 2 or a rear wall 3 and at least one of the parts having a large transverse dimension, respectively. Bonding is formed between the side walls 4 and 5 to form a more satisfactory grip for the user.

It should be appreciated that the first corner wall 8 and the second corner wall 9 may be disposed at any angle between the front wall 2 or the rear wall 3 and the respective side walls 4, 5. .

In the embodiment shown in FIGS. 5A and 5B, the first corner wall 8 and the second corner wall 9 are interposed between the front wall 2 and the respective side walls 4, 5, respectively.

In the embodiment shown in FIGS. 7A, 7B, 11A, 11B, the first corner wall 8 and the second corner wall 9 have the same side wall 4 and their respective front walls 2 and rears. It is interposed between the walls 3, respectively.

In the above-described embodiment, the side walls 4, 5 or the front wall 2 or the rear wall 3 interposed between the first corner wall 8 and the second corner wall 9 are in the main direction (“A”). It should be appreciated that the direction of inclination " B "

Preferably, the side walls 4, 5 or the front wall 2 or the rear wall 3 interposed between the first corner wall 8 and the second corner wall 9 have their inclined sides at the first corner wall. It has the shape of the parallelogram formed by the edges 8a, 8b, 9a, 9b of 8 and the second edge wall 9, respectively.

In the embodiment shown in FIGS. 9A and 9B, the first corner wall 8 is interposed between the front wall 2 and the side wall 4, while the second corner wall 9 is the rear wall 3. ) And the other side wall 5, ie they are located along the diagonal plane of the packet 1.

Thus, in this embodiment, both the front face 2, the rear face 3 and the side faces 4, 5 have a trapezoidal shape.

Advantageously, in this way, the packet is particularly easy to grip since the beveled edge walls 9, 8 are formed in the area where they are gripped by the user.

Preferably, the packet 1 (FIGS. 1 to 8 a) comprises a pair of first corner walls 8 and a pair of second corner walls 9.

 Thus, in these embodiments, the packet has four corner walls 8, 9, which completely replace the vertically sharp edges of the typical packet. In a form similar to the embodiment described above (as well as the object of the present invention), each first edge wall 8 holds substantially constant peripheral extension of each section traversing the main direction "A". In a manner complementary to the shape of each second edge wall 9.

In the embodiment of FIG. 1, each first edge wall 8 traverses the front wall 2 and is also different from the first edge wall 8 with respect to the intermediate plane parallel to the main direction “A”. And symmetry. Moreover, in that embodiment, each second corner wall 9 is symmetrical with the other second corner wall 9 with respect to the intermediate plane described above.

In other words, each first edge wall 8 and / or second edge wall 9 crosses the front wall 2 and is also different from the other first corner with respect to the intermediate plane parallel to the main direction (“A”). It is symmetrical with the wall 8 and / or with the second corner wall 9.

Alternatively, for example in the embodiment shown in FIGS. 7A, 7B, the first corner wall 9 is parallel to the main direction "A" and also the bottom wall 7 [of the packet 1 [ Or top surfaces 6, which are symmetrical with respect to the plane joining the two opposite vertices.

Similarly, the second corner walls 9 are symmetrical to one another with respect to the plane.

Basically, each of the first corner wall 8 and / or the second corner wall 9 is parallel to the main direction "A" and also two opposite vertices of the bottom wall 7 or the top wall 6. It is symmetrical with the other first edge wall 8 and / or the second edge wall 9 with respect to the plane to which it is bonded.

As already described, but without limiting the scope of the present invention, the illustrated embodiments are all directed to rigid packets for hinged-cover type tobacco articles.

As a result, the packet has a box body 10 having an upper edge 10a forming an opening 10b for access to a compartment "V" for containing a tobacco article "S", and an upper edge ( And a lid 11 hinged to the box body 10 at 10a). In particular, with reference to, for example, FIGS. 1 and 2B, the lid 11 is hinged along the upper edge 10a at the rear wall 3. In this way, the lid 11 can be freely rotated with respect to the box body 10 between the position in which the access opening 10b is closed and the position in which the access opening 10b is open.

With this in mind, the first corner wall 8 and the second corner wall 9 (or the first corner wall 8 and the second corner wall 9 in the case of pairs) are partly onto the box body 10. And partially extends over the lid 11.

Alternatively, each of the first corner wall 8 and the second corner wall 9 may be manufactured only on the box body 10 (FIGS. 10A, 10B) or only on the cover 11. (Not shown).

In particular, the box body 10 extends along the main direction " A " and also has a front face which forms part of the front wall 2, a rear face which forms part of the rear wall 3, side walls 4, A pair of sides forming part of 5) and a bottom side forming bottom wall 7 of packet 1.

Similarly, the lid 11 has a front face which forms part of the front wall 2, a rear face which forms part of the rear wall 3, a pair of side surfaces which form part of the side walls 4, 5, And an upper face which forms the upper wall 6 of the packet 1.

When it is in the closed state, the faces of the lid 11 are complementary to the faces of the box body 10 to form the wall of the packet 1.

The packet 1 also comprises a collar 12 which is connected to the upper edge 10a of the box body 10 in such a way that it rises from the access opening 10b.

The collar 12 is substantially U-shaped in a manner that forms a central notch for withdrawing tobacco articles (cigarettes).

The collar 12 thus has two side walls 12a and 12b and a front wall 12c having an upper edge notched to form a “U” shape.

With this in mind, the collar 12 is formed in the lid 11 and is to be matched with the corresponding portions 8c, 9c of the edge walls 8, 9 superimposed thereon when the lid 11 is in the closed state. At least one corner wall 13, 14 formed.

Without a side wall, the collar 12 has the same number of edge walls 13, 14 as the number of edge walls 8, 9 of the packet 1 associated with the front wall 2.

As a result, in the embodiment shown in FIGS. 1, 5A, 5B, 7A, 7B, 12A, 12B, and 13, the collar 12 has two corner walls 13, 14. .

In the embodiment shown in FIGS. 9A, 9B, 11A, and 11B, the collar 12 has a single edge wall 13.

The above-mentioned packet 1 is preferably made of a flat blank 100 made of cardboard or the like, which also forms the object of the present invention. The blank 100 has an axis "C" of the longest extension corresponding to the main direction "A" of the packet 1 and is also substantially rectangular in shape.

In particular, the blank 100 is continuously positioned along the direction ("C") of the longest extension, which is each next connected by a fold line 102 traversing the direction ("C") of the longest extension of the blank. A plurality of panels 101 are included.

The panel 101 forms the front wall 2, the rear wall 3, the top wall 6, and the bottom wall 7 of the packet 1.

Moreover, the blank 100 comprises a pair of tongues 103a, 103b located opposite one another of one or more panels 101, each of which tongue 103a, 103b contains a packet 1. To form the inner or outer sidewalls of the side walls 4, 5.

According to the invention, the blank 100 also comprises at least one first tab 104 and a second tab 105 interposed between the tongues 103a and 103b and the respective panels 101, respectively. do.

Each tab 104, 105 has a transverse dimension that can vary along the direction of the direction “C” of the longest extension of the blank 100.

Similar to the foregoing, the term "transversal" is used to mean a dimension that traverses (in particular vertically) the direction of the direction "C" of the longest extension of the blank 100.

More specifically, each tab 104, 105 extends between the first pleated lines 104a, 105a and the second pleated lines 104b.

In particular, each of the tabs 104, 105 is provided on each panel 101 by first fold lines 104a, 105a and also on each tongue 103a, 103b by second fold lines 104b, 105b. Is connected to.

As a result, the measurement of the distance between the two fold lines 104a, 105a, 104b, 105b of the single tab 104, 105 may vary along the direction "C" of the longest extension.

It should be appreciated that the fold lines 104a, 105a, 104b, 105b form the edges 8a, 8b, 9a, 9b of the edge walls 8, 9 of the packet 1.

Thus, to at least partially form the first corner wall 8 and the second corner wall 9 of the packet 1, the first tab 104 has a shape complementary to that of the second tab 105. .

Accordingly, the second pleat line 104b of the first tab 104 forms a profile complementary to the second pleat line 105b of the second tab 105.

In the embodiment where the edge walls 8, 9 extend substantially longitudinally along the entire packet 1, the blank 100 comprises a pair of first tabs 104 and one respectively associated with the panel 101. A second tab 105 of the pair.

Each first tab 104 has a second associated with making the cross dimension of the blank constant with the other first tab 104 aligned therewith to form a single first edge wall 8 of the packet 1. Complementary to both tabs 105.

Similarly, each second tab 105 has a constant transverse dimension of the blank and other second tabs 105 aligned therewith to form a single second edge wall 9 of the packet 1. Complementary to all associated first tabs 104.

In the embodiment where the packet 1 has four edge walls 8, 9 extending substantially longitudinally along the entire extension of the packet 1, the blank 100 has eight tabs 104, 105. It includes.

In particular, the blank 100 comprises four first tabs 104 of associated and complementary pairs and four second tabs 105 of associated and complementary pairs.

In addition, each pair of first tabs 104 is associated with and complementary to a corresponding pair of second tabs 105.

Preferably, each first tab 104 and / or second tab 105 has a triangular or trapezoidal shape.

In some embodiments, each first tab 104 and / or second tab 105 has a curved surface.

The present invention achieves a set goal and also brings important advantages.

Indeed, due to the presence of a corner wall with complementary extensions, the packet can be easily gripped and at the same time simple to pack.

Indeed, due to the same and opposite extensions of the pair of (first and second) corner walls, the peripheral extension of the packet remains constant over the entire longitudinal extension of the packet.

Moreover, the use of inclined edge walls in this way eliminates at least partly the presence of sharp edges where a typical packet wears the user's clothing.

Finally, it should be recognized that the particular shape of the packet makes it particularly satisfying and innovative in terms of appearance.
